a quadrilateral
A 2D shape that has four sides and is thirteen letters long is a quadrilateral.
In geometry, a tridecagon (or triskaidecagon) is a 13-sided (and angled) polygon.
Shapes with 12 to 20 sides are named as follows: a 12-sided shape is called a dodecagon, a 13-sided shape is a triskaidecagon, a 14-sided shape is a tetradecagon, a 15-sided shape is a pentadecagon, a 16-sided shape is a hexadecagon, a 17-sided shape is a heptadecagon, an 18-sided shape is an octadecagon, a 19-sided shape is a nonadecagon, and a 20-sided shape is an icosagon.

a quadrilateral
A 2D shape that has four sides and is thirteen letters long is a quadrilateral.
A 13 sided polygon is called either a triskaidecagon or tridecagon.
In geometry, a tridecagon (or triskaidecagon) is a 13-sided (and angled) polygon.
Shapes with 12 to 20 sides are named as follows: a 12-sided shape is called a dodecagon, a 13-sided shape is a triskaidecagon, a 14-sided shape is a tetradecagon, a 15-sided shape is a pentadecagon, a 16-sided shape is a hexadecagon, a 17-sided shape is a heptadecagon, an 18-sided shape is an octadecagon, a 19-sided shape is a nonadecagon, and a 20-sided shape is an icosagon.
A 13 sided shape is a tridecagon or tristedecagon. The roots to this word are tri (meaning 3) and dec (meaning ten). 3 + 10 = 13.
